Nine blades and a box of radiator screws sound like a strong case for mounting the Nyota Ultra straight onto a radiator without a second thought. Neither detail actually settles that question, and treating blade count as a performance figure is a common way to plan cooling around a number that was never designed to answer it.
Quick Answer
The Nyota Ultra lists nine blades and includes radiator mounting screws, but neither settles whether it suits a radiator specifically. No static-pressure claim exists for this model, and blade count on its own is a design detail rather than a predictor of how a fan performs against restricted airflow.
🌀 What blade count actually tells you
The number of blades on an impeller affects how the fan is arranged and can shape its general airflow character, but it does not, by itself, describe how the fan performs when air is forced through something that resists it. A nine-blade design is one input among several that determine real-world performance, alongside blade shape, spacing, and speed, none of which the blade count alone communicates.
🧱 Why static pressure is the figure that actually matters here
A radiator's dense fin stack resists airflow far more than open space does, and static pressure is the specific measurement that describes how well a fan continues to push air through that kind of resistance rather than into a clear path. It is a different figure entirely from airflow, and it is the one that would normally answer whether a given fan is well suited to radiator duty.
📄 What the listing actually publishes
For this fan, the confirmed figures are 58.5 CFM airflow, an 800 to 2000 RPM PWM speed range, 6 to 30 dBA noise, the nine blades already mentioned, and a hydro bearing. No static-pressure claim exists for this model, which means the listing itself does not contain the number that would settle the radiator question either way.
🌡️ How to actually settle it for your own build
Mounting the fan to a radiator using the included screws is entirely possible, and plenty of builds do exactly that, but the outcome depends on factors the listing does not describe. Measuring coolant temperature or component temperatures once the fan is installed is the only test that reflects your specific radiator, its fin density, and the rest of your cooling loop. More blades does not reliably mean more pressure on its own, since shape, spacing and speed all play a part too, which is another reason the count alone cannot be treated as a verdict.

Frequently Asked Questions
What does the Ultra's nine-blade count actually indicate?
How the impeller is arranged, which shapes general airflow character without directly describing performance against restriction.
Why is static pressure the figure that matters for radiators?
Because a radiator's fin stack resists airflow, and static pressure specifically measures how well a fan pushes through that kind of resistance.
Is a static-pressure figure published for this fan?
No. No static-pressure claim exists for this model, so the listing does not settle the radiator question directly.
Does including radiator screws imply the fan performs well there?
No. The screws are mounting hardware provided as a convenience, not a statement about performance once mounted.
Can the fan still be used on a radiator anyway?
Yes, it can be fitted, but the result needs to be judged from your own build's temperatures rather than assumed from the listing.
Would more blades automatically mean better radiator performance?
Not reliably. Blade shape, spacing and speed all contribute alongside count, so the number alone is a weak predictor.
